Dr. Mishkat Bhattacharya is a Professor of Physics and Astronomy at the Rochester Institute of Technology. He is a program faculty in the Center for Imaging Sciences at RIT and a member of the Center for Coherence and Quantum Optics at the University of Rochester. Dr. Bhattacharya received a B.Tech degree in Engineering Physics from the Indian Institute of Technology, Bombay, and a Ph.D. degree from the University of Rochester. He held postdoctoral positions at the Georgia Institute of Technology, the University of Arizona, and the University of Maryland, College Park, before joining RIT in 2011. Dr. Bhattacharya teaches freshman mechanics, modern physics, quantum mechanics, and quantum optics. He reviews regularly for journals such as Physical Review Letters, the Journal of Physics B, and the American Journal of Physics.

The Bhattacharya group is broadly interested in light-matter interactions from the perspective of fundamental science as well as technological applications. Currently, it is focused on the interplay of electromagnetic modes of radiation, such as laser light, with nanofabricated components, such as mechanical oscillators and rotors. Major aims are the cooling of macroscopic objects into the quantum regime and establishing the limits to quantum sensing of mechanical displacement, force, and rotation, for example. These investigations are expected to test the foundation of quantum mechanics as well as to yield next-generation sensors that circumvent the limits posed by quantum mechanics to their sensitivity. Some of the group efforts also go towards investigating other related platforms for quantum technologies such as ultracold atoms and molecules. The work is fully theoretical, involving mostly analytical calculations, using the techniques of quantum optics and atomic physics, and some medium-scale numerical work. Close collaborations exist with experimental groups locally, nationally, as well as internationally. The program involves researchers at every level, including undergraduate, master's, and doctoral students as well as postdoctoral scholars. Recent funding sources include the Research Corporation for Science Advancement, the Office of Naval Research, and the National Science Foundation.

    RIT researcher collaborates with UR to develop new form of laser for sound

    The optical laser has grown to a $10 billion global technology market since it was invented in 1960, and has led to Nobel prizes for Art Ashkin for developing optical tweezing and Gerard Mourou and Donna Strickland for work with pulsed lasers. Now an RIT researcher has teamed up with experts at the University of Rochester to create a different kind of laser – a laser for sound, using the optical tweezer technique invented by Ashkin.
